Not making new lines. Distribution block is just to transfer the fluid to the corners, no prop valve in an all drum/disc one. No need for a prop valve as told by Dr. Diff if the front brakes are bigger than front too. I have a prop valve that will be added in at some point, but I’m not trying to reinvent the entire wheel, just pieces of it. Stock lines work, only one that might need work is on the shortened housing, otherwise this system is a bolt together kit. The idea is to build the car with as little custom stuff as possible, so it’s easy to order and replace, cut down replacement time
